This egg in a bottle project from Science Fair Adventure would be a great fit for the upper elementary/early middle school crowds (grades 5 and 6). Using a peeled hard-boiled egg, a bottle, and matches, you'll learn about the various properties of air pressure that have a direct affect on weather, as well as other concepts like aerodynamics. How? By using these same properties to get an egg into and out of a bottle undamaged. For the full project write-up, suggestions for completion, and a brief conclusion, be sure to visit Science Fair Adventure! [NOTE: This project does call for a hard-boiled egg and the use of matches. For safety, have an adult around for help and supervision!]
